This project continues work in “Soil and Groundwater Investigation and Verification Project” of New Taipei City. Work contents include regular soil and groundwater monitoring work, monitoring well external appearance patrol, maintenance and repeal, gas station online declaration and on-site inspection, soil and groundwater pollution site supervision, verification and inspection, scope of pollution site broadening investigation, pollution verification on prosecutors care and public nuisance dispute and emergency response, advocacy and administrative work.
28 groundwater samples were sampled, with work achievement of 100 % in groundwater sampling work category in project contract. Among all groundwater samples, the F00057 show higher concentration of VC (0.0659 mg/L), the F00134, F00189 and F00224 are still contaminated by CIS-1,2DCE (0.477 ~ 1.86 mg/L), the results showed that no pollutants had not spread out in the Shulin Industrial Park. The F00370 Mercury concentration (0.12 ~ 2.2 mg/L) still exceeds control standards.
A total of 272 monitoring wells have carried out monitoring well external appearance patrol and maintenance. The project maintained 26 groundwater monitoring wells, abolished 5 monitoring wells, and maintained 11 wells internal functions.On regular declared and modified monitoring document of gas station, 739 documents were examined. 11 gas stations on-site verification work were carried and all field records were uploaded to “Soil and Groundwater Information Management System”. Each pollution Control Site is patrolled at least once a month, and the pollution Remediation Site is patrolled twice a month, 687 Sites were patrol and supervised, all field records were uploaded to “Soil and Groundwater Information Management System”.4 Control Sites were verified, 4 repopulation soil site were verified, 16 sites were investigated and 1 site were monitored. Soil and Groundwater Pollution Remediation Act Article 8 and 9, 43 on-site inspections and 54 cases reviewed. Held 4 regulatory symposiums, and handle them online in response to COVID-19, and cooperate with the 20th anniversary environmental exhibition.
Soil and groundwater pollution incidents will still occur, and subsequent pollution investigation and verification work is necessary.
